Slave autoconfiguration broken: chains-zeroconf-discoverd not working

[chrisaq]

Things have happened with zeroconf.py breaking the discoverd program.
amqp.py is not being generated, and slave will not connect automatically.

Temporary fix is to edit amqp.conf manually for slaves.

While waiting for this to be fixed, use the AMQP environment variable to specify ip/port for the master node.
